Cleaning
Possible malfunctioning and damage to the panels caused by pollution.
Before mounting the roof plate of the fan:
Clean polluted areas in the fan box. To do this, use a vacuum cleaner and
a lint-free cloth. If necessary, moisten the cloth, use a mild household
cleaner, and dry properly at the end.
Some parts and surfaces of the switchgear are greased for functioning. Do
not remove the grease there; do not clean the parts and surfaces.
If greased areas are dirty, clean the dirty area and grease again according
to the maintenance instructions.
INFORMATION
Before commissioning the switchgear, the fan box may only be permanently closed
by bolting the roof plate of the fan together under the following conditions:
•
The inside area of the fan is free from foreign objects and pollution
•
All previous assembly work inside the fan area has been fully and properly
completed
Verify completeness and correctness of the previous assembly work in the
inside area of the fan. For this purpose, also check the tightening torques
of the bolted joints, and correct the torques if required
Record the proper condition of the inside area of the fan after bolting
together, so that this is clear without any doubt before commissioning the
switchgear.
